During the eruption, almost all air traffic was canceled for the next 5 days, more than 100,000 flights. Eyjafjallajökull (also known as Eyjafjöll) is located west of Katla volcano. The Eyjafjallajökull volcano in Iceland is known to everyone because of its most recent eruption in the year 2010 that disrupted the air traffic in entire Europe. Started: April 14th, 2010 Ended: June 23rd, 2010 . The behavior of Eyjafjallajökull might be typical for such moderately active volcanoes. Iceland’s capital… After a two-day pause, the volcano began to erupt again on April 22nd. You will receive a verification email shortly. Still, why did Iceland’s Eyjafjallajökull cause so much trouble back then, and why even today are its other volcanoes often causing similar worries among airlines and … As explosive as Eyjafjallajökull proved, it is actually only a moderately active volcano — that is, one that erupts once every few centuries or even millennia, explained volcanologist Freysteinn Sigmundsson at the University of Iceland. The ash plume that was created reached a height of 11 km. Eyjafjallajökull first erupted on March 20, 2010, in a fiery display that sent fountains of lava shooting high into the air and ribbons of lava flowing down cliff faces. Future US, Inc. 11 West 42nd Street, 15th Floor, Sigmundsson and an international team of collaborators had tracked Eyjafjallajökull over the last two decades of intermittent volcanic unrest using satellite radar, GPS receivers and seismic monitoring. Katla did not display any unusual activity (such as expansion of the crust or seismic activity) during the 2010 eruptions of Eyjafjallajökull, though geologists have been concerned about the general instability of Katla since 1999. The last major eruption occurred in 1918, so it is long overdue. "There was not one main magma chamber active under the volcano capturing magma in 18 years of unrest preceding the eruption, as is often envisioned in models for the most active volcanoes on Earth. This enabled them to deduce how the volcano swelled to within a few millimeters accuracy due to the flow of magma within in the months before and after it became active. Located on a constructive plate margin. Weird sounding volcano, Eyjafjallajökull is one of the most famous places in Iceland. Visit our corporate site. Additional localised disruption continued into May 2010. For an optimal experience visit our site on another browser. BGS scientists respond to volcanic eruptions and contribute to the Scientific Advisory Group in Emergencies (SAGE). Rather, two or more discrete magmatic sources were involved, with magma of different composition.". The volcano Eyjafjallajökull (AYA-feeyapla-yurkul) burst to life in March after nearly two centuries of dormancy. However, the magma chamber that deflated in Eyjafjallajökull during the explosive April eruption was not the one that filled up right beforehand. By comparison, Hekla is a mere infant at just 8800 years of age. The name Eyjafjallajökull is derived from an Icelandic phrase meaning … Please refresh the page and try again. Wiki User Answered . Here, you can read more Eyjafjallajökull facts. It started up again a few weeks later in June but the activity was very limited. The last eruption in the Eyjafjallajokull glacier, in 1821, spread to Katla, causing serious flooding. Thank you for signing up to Live Science. New York, I've searched all over the internet and can't find it for some reason. Sigmundsson and an international team of collaborators had tracked Eyjafjallajökull over the last two decades of intermittent volcanic unrest using satellite radar, GPS receivers and seismic monitoring. It then erupted in April, spewing a huge plume of ash that created phenomenal lightning displays, colored sunsets a fiery red across much of Europe, and forced flight cancellations for days. Sigmundsson and his colleagues detailed their findings Nov. 17 in the journal Nature. The country’s government, still reeling from the financial crisis, chose to bring in UK consulting firm Brooklyn Brothers to help mitigate the impact of the negative coverage. Shares. Records show eruptions in 920, 1612 or 1613, 1821–23, and 2010. The cause of Eyjafjallajökull's explosive eruption seemed to be the meeting of one body of magma, made up mostly of the common volcanic rock basalt, with another type of magma within the volcano, consisting largely of silica-rich trachyandesite. From the initial eruptive activity at Eyjafjallajokull volcano in 2010, that was a lava producing eruption 20 March - 12 April, preceding the explosive eruption. NY 10036. Each of the eruptions of Eyjafjallajökull in 920, 1612, and 1821–1823 has preceded an eruption of Katla. The eruption of Eyjafjallajokull in May 2010 resulted in the grounding of thousands of flights all over Europe. why did the Eyjafjallajökull volcano erupt? It has been an active volcano since many decades. On the boundary can be found numerous volcanoes and these erupt fairly frequently. Eyjafjallajökull Volcano. © "One of the surprises was the complexity of the plumbing system," Sigmundsson said. The plates are moving apart at a rate of 1-5cm a year. 2010-12-10 09:45:01 2010-12-10 09:45:01. Recently, there have been peaks in these warning gases, which can indicate an eruption is on the way. 23 24 25. The cause of Eyjafjallajökull's explosive eruption seemed to be the meeting of one body of magma, made up mostly of the common volcanic rock basalt, with another type of magma within the volcano, consisting largely of silica-rich trachyandesite. The volcano Eyjafjallajökull (AYA-feeyapla-yurkul) burst to life in March after nearly two centuries of dormancy. Live Science is part of Future US Inc, an international media group and leading digital publisher. "Our research shows that mapping out magmatic plumbing systems is important to correctly interpreting potential precursors to eruption. So how did Iceland turn things around? Why did the eruption happen? All hope was not lost, however, and hope came from a most unlikely source: the eruption of Eyjafjallajökull in the spring of 2010. The situation of a slowly growing magmatic intrusion inside a volcano can quickly go out of bounds if such an intrusion hits a body of magma of different composition — then a sudden explosive eruption can occur, as in Iceland earlier this year.". The situation of a slowly growing magmatic intrusion inside a volcano can quickly go out of bounds if such an intrusion hits a body of magma of different composition — then a sudden explosive eruption can occur, as in Iceland earlier this year.". "Our research shows that mapping out magmatic plumbing systems is important to correctly interpreting potential precursors to eruption. It most recently erupted in 2010. The 2010 eruption of Iceland's Eyjafjallajökull volcano had a huge impact on air travel, changing the assessment of risk by the aviation sector and catalyzing new lines of scientific investigation. Eyjafjallajökull did not behave like a highly active volcanoes when one of those volcanoes (think Kilauea) is going to start erupting. KEY INFORMATION. Rather, two or more discrete magmatic sources were involved, with magma of different composition.". Over time, the earthquakes rose towards the surface, and land near the volcano rose at least 40 millimeters (2 inches)—both indications that magma was moving underneath the volcano. There are several large volcanoes in Iceland, and when they erupt they are likely to have considerable effects across western Europe and beyond. A peek into the roots of the eruption of the Eyjafjallajökull volcano in Iceland earlier this year that disrupted flights across Europe could shed light on the mysterious behavior of volcanoes that have been dormant for centuries. Convection currents are driving apart the North American plate and the Eurasian plate. Why did Eyjafjallajökull erupt? When it comes to a typical eruption of highly active volcanoes, scientists have learned over the years that magma chambers within the volcano gradually fill up beforehand and rapidly deflate as pressure is released, deforming the surface. Location : The eruption began on 20th March 2010 and ended 7 months later in October 2010. I guessed this in my homework: The volcano is located on a constructive plate boundary. Iceland sits on a boundary between two tectonic plates. The plate boundary is pulling apart at a rate of 2 cm a year. This article was provided by OurAmazingPlanet, a sister site of LiveScience. "There are many such volcanoes in the world, including many on the circum-Pacific 'Ring of Fire' volcanic belt, including volcanoes in the U.S. West, Kamchatka [in Russia] and the Andes," Sigmundsson told OurAmazingPlanet. In the past, the UK has been affected by volcanic eruptions in Iceland, the most notable being the 2010 Eyjafjallajökull and 2011 Grímsvötn eruptions, which resulted in disruption of air traffic in the North Atlantic and Europe. As of August 2010, Eyjafjallajökull … Eyjafjallajökull is an active volcano in southern Iceland, lying within the country’s East Volcanic Zone. Case study - eruption in a developed country: Eyjafjallajökull. This enabled them to deduce how the volcano swelled to within a few millimeters accuracy due to the flow of magma within in the months before and after it became active. Its eruption in 2010 interfered with European and transatlantic flights for two weeks. Eyjafjallajokull volcano, Icelandic volcano whose name is derived from an Icelandic phrase meaning ‘the island’s mountain glacier.’ Lying beneath Eyjafjallajökull (Eyjafjalla Glacier), its summit rises to 5,466 feet (1,666 meters) above sea level. Iceland has several volcanoes and is situated on two tectonic plates – the North American plate and Eurasian plate. When it comes to a typical eruption of highly active volcanoes, scientists have learned over the years that magma chambers within the volcano gradually fill up beforehand and rapidly deflate as pressure is released, deforming the surface. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. Until now, it was uncertain as to whether, or how "colder," moderately active volcanoes such as Eyjafjallajökull behaved any differently from their hotter and more active kin during eruptions, since they erupt less often for researchers to study. The geologic processes that trigger an actual eruption are not yet well understood, says Feigl. There was a problem. "There are many such volcanoes in the world, including many on the circum-Pacific 'Ring of Fire' volcanic belt, including volcanoes in the U.S. West, Kamchatka [in Russia] and the Andes," Sigmundsson told OurAmazingPlanet.
